Topic	Sediment: Matthews Landslides Delivered by Sub-basin 1921-2000

 

Caption:  The chart above shows the occurrence of delivered landslides during the study period for each Big River sub-basin; derived from Matthews and Associates (2001). Estimates are generated from aerial photographs. The greatest sediment delivery appears to have occurred during the 1937-1952 and 1953-1965 periods. Middle Big River, Lower Mainstem, South Fork and Daugherty Creek sub-basins show the most recent landslide activity. The actual number of slides in the 1921-1936 period is likely an underestimate, since 1936 photo coverage for the eastern half of the watershed was unavailable. See Info Links for more background information and links to references.
